support D
The support of a torus-invariant Weil divisor is the set of irreducible torus-invariant divisors which appear with nonzero coefficients in the unique expression for this divisor. In this package, we encode this information by indexing the irreducible torus-invariantdivisors that appear with a nonzero coefficient. The indexing of the irreducible torus-invariant divisors is inherited from the indexing of the rays in the associated fan.
